GeoCore is a technical toolkit for surveying, cadastre, GIS and civil design, integrated directly into AutoCAD, BricsCAD, ZWCAD, GstarCAD and CADMATE.

GeoCore keeps the interface clear and predictable: the essential information remains visible at all times, while the commands are grouped logically for fast work directly inside CAD.

General interface: the GeoCore tab and the CAD status bar display the drawing scale and the drawing unit (m/cm/mm) permanently.

Ribbon commands grouped logically: the menu is simple, intuitive and free of unnecessary buttons, so the important functions remain easy to find even in dense production drawings.

Points and Surfaces tab: user preferences for the display of GeoCore CoGo/survey points and for surface-related operations can be set without leaving the current drawing environment.

General preferences: you can quickly define layer names, colors, sheet frames and title blocks, including custom variants with your company branding.

Style and template import/export: the preferred visual standard can be shared across the whole team, so all users draw consistently. Alongside GeoCore settings, native CAD styles can also be imported and exported.

The points module covers the entire workflow for importing, checking, configuring and managing survey/CoGo points directly in CAD, without unnecessary intermediate processing.

Survey and CoGo point operations: GeoCore provides a complete toolset for CoGo and topographic points, from import and validation to labeling, organization and drawing control.

Point import: there is no need to waste time editing coordinate files manually. GeoCore detects the file content automatically and suggests the most suitable import method.

Automatic analysis of coordinate files: even when the structure is detected automatically, you can still choose the exact columns you want, without getting lost in NEZ/ENZ fields, northing/easting, point name, elevation or code.

Complete information, full transparency: file preview is live, and the status line at the bottom of the window always shows import statistics, including removed, renumbered or invalidated points.

The GeoCore CoGo point is a block entity accompanied by a multileader label that can display the point name, elevation and code. From the combo box available in the points panel of the Ribbon you can show or hide the name, elevation, code and leader independently.

The displayed fields can be adjusted at any time, and once the plan is finalized they can be kept or removed before the sheets are handed over to other departments such as civil design.

New point insertion

Create new points with elevations computed by linear interpolation between two existing points.

Insert new points automatically with interpolated elevations based on the nearest valid elevation points along a route.

Insert points automatically on entities of all types, including at intersections between entities.

Arrange labels, renumber points, search by name or code, run operations on all points of the same code, move them in 2D or 3D, and convert native CAD points into GeoCore points.

Existing blocks can also be converted into GeoCore points, which is useful when importing drawings produced with other applications.

Parcel and route tabular data is the module that lets you select parcel surfaces, land lots or utility routes and generate clear tables directly from the actual geometry already present in the drawing.

For parcels and land lots, GeoCore can summarize areas, identifiers, names and other information required for checking, approval or formal delivery. The result is a coherent table ready for cadastral documentation, parceling plans or field reports.

For utility routes, you can work with power lines, sewer networks, fiber-optic routes, telecommunications, water pipes, gas pipelines and similar alignments. Once the entities are selected, the application builds the table automatically from the real route geometry.

The generated tables can include survey coordinates, elevations, lengths and distances between segments, both for straight alignments and for curved geometry. This greatly reduces repetitive manual calculations when preparing technical appendices.

Practical value: the module is especially useful for cadastral documentation, utility design, site plans, coordinate listings and any project where accurate tabular output must be produced quickly and checked easily.

The automatic subdivision module lets you split areas directly in CAD, without unnecessary auxiliary construction and without repetitive manual calculations.

Simple parallel and perpendicular splits: you can either enter the target area numerically or pick a forced point directly on screen, and the result updates dynamically while the command is running.

Split by parallel sides: select multiple adjacent parcel sides and GeoCore will build the new subdivision boundary automatically while respecting the existing geometry.

Multiple subdivisions: for repetitive lot creation, one surface can be subdivided into several parallel or perpendicular plots, with control over the number of lots, the resulting areas and the street frontage.

Automatic definition and labeling: after the lots are generated, the application helps define the resulting areas, review them quickly and label each parcel clearly for cadastral or urban planning deliverables.

Export and import parcel boundaries and areas, routes and polylines, as well as survey points, in KML format for Google Earth, Google Maps, ArcGIS Online and other GIS platforms. GeoCore converts coordinates automatically from STEREO 70 to WGS 84 for direct global use.

Compatibility with GIS workflows: QGIS, ArcGIS Pro / ArcMap, Global Mapper, Leica Infinity, Trimble Business Center and other systems that rely on quick geospatial data exchange.

Field and mobile GIS applications:

Avenza Maps: supports offline maps and uses KML for field collection of GPS points and routes on phones and tablets.

Locus Map / OsmAnd: useful for navigation and semi-professional field work, with KML-based routes and point import.

Pix4D / DJI Terra: photogrammetry tools that use KML for importing mission boundaries and planning geo-referenced drone flights.

LandXML (.xml) is the universal standard in infrastructure, surveying and construction for transferring 3D data such as surfaces, alignments, profiles, parcels and utility networks. It enables direct communication between design software, field instruments and automated machine workflows.

LandXML is the exchange format used by most modern surveying equipment, total stations, GPS/GNSS receivers and automatic machine guidance systems. It supports the accurate 3D transfer of TIN surfaces, road alignments, profiles and staking points directly from design applications to field equipment.

Surveying and geodetic equipment

Field instruments rely on LandXML to import road axes, digital terrain models and layout points.

Robotic and manual total stations: import design data directly for field staking.

GNSS/RTK receivers: use LandXML surfaces to guide the operator in real time for cut and fill elevations.

3D laser scanners and UAVs: can feed point-cloud-derived mesh/TIN surfaces into LandXML workflows.

Construction machinery and machine control

Modern machines load the LandXML file into the onboard computer, and the hydraulic system adjusts the blade or bucket automatically according to the 3D design.

Bulldozers and motor graders: use LandXML for automatic leveling of road layers or working platforms.

Excavators: display the 3D trench or foundation model directly in the cabin.

Asphalt pavers and compactors: receive the longitudinal and cross profiles required to place layers with precise geometry.

Compatible guidance ecosystems: Trimble Earthworks / GCS900, Leica iCON site / iCON grade, Topcon 3D-MC / MC-Max.

Leica Geosystems: total stations and GNSS receivers from the Leica Viva, Nova and Captivate families use LandXML through Leica Captivate or SmartWorx Viva, while Leica iCON 3D machine guidance imports LandXML directly for excavation and grading surfaces.

Trimble: GNSS receivers and robotic total stations running Trimble Access support LandXML alignments, profiles and surfaces natively. In construction, Trimble Earthworks and Trimble GCS900 consume LandXML-based workflows prepared in Trimble Business Center.

Topcon and Sokkia: MAGNET Field imports LandXML directly for road staking and surface work, while Topcon 3DMC uses it for 3D guidance of dozers, graders and pavers.

OEM machines with factory-integrated guidance: manufacturers such as Caterpillar, Komatsu and John Deere rely on digital terrain models coming from open formats such as LandXML, either directly or after a lightweight conversion to the display’s native format.

GeoCore exports Trimble DSZ, SVD and SVL directly, without requiring Trimble Business Center, Trimble FileFlipper or any other Trimble utility for intermediate conversion.

DSZ: the modern Design File used by Trimble Earthworks and Trimble Siteworks. It acts as a complete project package, ready for direct upload to machine control systems and field controllers, with the 3D surface, guidance linework and project metadata inside a single file.

SVD: the 3D surface file. It is used to import and run the digital terrain model or the design model so that the machine or field crew can perform excavation, fill, grading and verification work on the basis of a clear surface model.

SVL: the linework and guidance file. It is used to import and display design lines, 2D/3D polylines, arcs, points and other visual references needed for staking, navigation and field tracking.

The modern Trimble workflow: Trimble documentation shows that Earthworks and WorksManager can use DSZ as a unified design file, while classic or compatible workflows can still use separate SVD for the surface and SVL for the linework.

What this means in GeoCore: the 3D model, surfaces, guidance lines and all required field elements can be prepared and exported directly from GeoCore in the target format required for upload to Trimble platforms, machine control systems or field transfer media.

Important: GeoCore does not need Trimble software to generate these deliverables. You can produce the target file directly for the chosen workflow and load it further into the Trimble ecosystem without an extra conversion step.

3D TIN modeling is the module dedicated to building and processing triangulated surfaces directly in CAD. GeoCore can generate TIN / Mesh / 3D Solid models quickly for surveying, design, earthwork quantities, site grading and machine control deliverables.

Generation from GeoCore CoGo points: coherent 3D models can be built rapidly even from very large survey datasets, with clear and controllable triangulation. The result can remain a Mesh entity or be converted into a 3D Solid depending on the required workflow.

Generation from 3D entities: GeoCore can also create TIN surfaces directly from existing geometry, so you do not have to start from classic survey points if the model already comes from 3D lines, contours or other prepared entities.

Slice, Trim and Cut operations: TIN models can be split by elevation planes, by planes defined through three points, by 2D/3D lines and polylines or by selected boundaries. This makes it easy to isolate zones, remove unwanted triangles and prepare the model exactly in the form required for analysis or delivery.

Practical value: this type of modeling is essential for terrain analysis, geometry checks, profile extraction, slope analysis, clipping of areas of interest and preparation of surfaces for exchange with field equipment or third-party software.

Contour lines make it possible to represent relief in three dimensions on a topographic plan and to read elevations, slopes and landforms such as valleys, ridges, hills or depressions clearly. In GeoCore they can be generated directly from the triangulation of survey points, in 2D or 3D, without requiring a prebuilt 3D model.

What are contour lines? They are imaginary lines connecting points with the same elevation relative to a reference level, usually mean sea level. The contour interval is the constant elevation difference between two successive contours. Major contours are thicker and labeled, while minor contours provide the intermediate detail.

Terrain interpretation becomes immediate: closely spaced contours indicate steep slopes, while widely spaced contours indicate flat or gently sloping terrain. This is essential for quick terrain reading and for correct decisions in design, staking and verification.

Practical applications: slope analysis, topographic profile extraction, cut-and-fill estimation, watershed delineation, runoff analysis and field navigation. Contour lines remain highly useful in infrastructure, agriculture, hydrology and outdoor navigation.

Why they still matter today: even in modern GIS and CAD workflows, contour lines remain fundamental. They underpin digital terrain models, are now generated with very high precision from LiDAR or photogrammetry, and are widely used in mapping, route planning and automated machine guidance.

Site Grading is the module dedicated to the rapid vertical layout of a parcel or working platform, based on the existing 3D model. You select the terrain boundary in plan, define the building footprint and choose the reference 3D model, and GeoCore prepares the geometry required to check and design the final grading elevation.

The workflow is straightforward: the parcel boundary is projected in 3D, the building footprint is positioned on the model, and the application generates the graded terrain shape according to the project conditions. The result is useful both for geometric verification and for preparing technical deliverables.

Practical value: you can review elevation differences quickly, analyze the relationship between existing ground and the designed platform, and estimate cut and fill volumes. The module is especially useful for yards, industrial platforms, quarries, access roads and other projects where terrain shaping must be controlled clearly and quickly.

Hypsometric map: Hypso generates clear hypsometric terrain representations, highlighting elevation differences through intuitive color intervals. It is ideal for fast relief analysis, identifying low and high areas, and presenting the terrain model in an easy-to-read format.

Slope map: creates slope maps from the digital terrain model and highlights areas with different inclinations. It supports stability checks, drainage analysis, infrastructure planning and risk identification. Slopes can be displayed in degrees or percentages.

Hillshade map: Hillshade creates a shaded relief representation by simulating light over the terrain surface. Select a 3D TIN model, choose the calendar month and local time, and GeoCore generates the 2D map and the 3D model.

Point QR quickly links survey points with QR codes, making field identification, checking and access to point information easier.

By scanning the code, users can view relevant data such as coordinates, descriptions and technical attributes. It is a practical way to improve point traceability and connect Civil 3D project data with site activity.

Point Cloud imports and uses LAS/LAZ point clouds, providing a precise base for terrain analysis, existing-surface modeling and field documentation.

LAS and LAZ files store detailed 3D point information such as coordinates, elevation, intensity, classification and other attributes. LAZ keeps the same data in a compressed format, making large projects easier to store and transfer.

Ground Filter separates natural ground points from vegetation, vehicles, equipment, buildings and other above-ground objects, producing a cleaner dataset for digital terrain models, contours, slope maps, hypsometric maps and volume calculations.

Terrain sections remain one of the most important deliverables in design, infrastructure and construction. GeoCore generates longitudinal and cross profiles directly from the terrain, without manual drafting and without unnecessary intermediate steps.

The longitudinal profile is used to follow the evolution of elevations along a route: roads, canals, utility networks, pipelines or other project alignments. It helps define slopes, foundation elevations and the exact relationship between natural ground and the proposed design.

Cross sections are essential for understanding the terrain shape across the route, checking side slopes, platforms, cuts and fills, and controlling construction geometry against existing ground.

Practical value: road and bridge designers use them to define slopes and design elevations, utility engineers use them for gravity flow and route checking, and site teams rely on them for fast control directly from the printed sheet, without navigating a complex 3D model.

Why they still matter: because they clearly show cut and fill volumes, elevation changes and project critical points. Even though the source data now comes from GPS, total stations, drones or LiDAR, 2D profiles and sections remain the practical and legal basis for checking, delivery and execution.

Flexible representation: the horizontal scale can remain equal to the plan scale, while the vertical scale can be amplified by 1x / 2x / 5x / 10x for easier reading of elevation differences.

The drawing tools in GeoCore are designed for the repetitive operations that appear daily in topographic, cadastral and cartographic sheets. Instead of wasting time on manual adjustments, you can work faster and more consistently directly in the drawing.

Dynamic dimensioning on polylines: the application can place lengths and useful information directly on polylines by following the real route geometry. This is especially useful for boundaries, alignments, utility routes and parcel outlines where distances must be shown clearly and quickly.

Text, symbol and conventional-sign alignment: texts and symbols can be oriented automatically along the direction of an entity so the drawing remains clean, readable and consistent. This is very useful in crowded plans where manual rotation consumes time.

Polyline editing: GeoCore simplifies geometry correction by allowing quick insertion or removal of vertices. This helps when refining boundaries, routes or area limits and you need precise control without complex editing steps.

Rectangular topographic/cartographic grid: a rectangular grid can be drawn automatically for framing, orientation and sheet presentation. The function is useful both for technical deliverables and for plans where spatial indexing must remain clear and consistent.

The practical result is a faster drafting workflow, cleaner drawings and a significant reduction of repetitive manual operations that normally consume time and may introduce presentation errors.

Sheets are essential for clear and orderly project delivery. GeoCore helps you prepare sheet layouts directly in model space, so the area of interest, the frame and the basic information are already organized for plotting and submission.

Automatic layout generation reduces the time lost on repetitive work. Based on the selected configuration, the application can create multiple layouts quickly and insert title blocks automatically, so the sheets are ready for completion, checking and export.

Control over frame and view extent: the exact area to be included on the sheet can be defined clearly, which makes the workflow suitable both for small jobs and for large, consistently aligned sheet sets.

Scaling and efficient organization: the number of sheets can be adjusted by choosing the drawing scale. This is especially useful for atlas-style sets, cadastral sheets, site plans or extended technical documentation.

Preview before generation: just like in modern atlas-sheet workflows, it is important to visualize the result before the final output is created. This helps avoid incorrect frames, clipped areas and misaligned layouts.

Practical value: the sheets module is highly useful for topographic, cadastral, urban planning and infrastructure documentation, where you need deliverables that are coherent, repeatable and easy to print or export to PDF.
